I was searching for a UPS for my computer and found one which says 1000W / 2000VA, DC 24V

This means connecting 2 x 12V batteries in series. My question is don’t UPS usually have batteries connected in parallel rather than series ?
Does connecting it in series or parallel affect the backup time ?
What are the advantages and disadvantaged of either setup (regarding UPS battery) ?
Thanks
If I do get it I’ll have to buy the batteries as a separate buy.
and connect them up myself. So how does connecting in series affect (if at all ) backup time compare to parallel and does connecting in series or parallel reveal the type or quality of the UPS ?
